Answer:
-8b^7 - 4b^5 + 5b + 16
Step-by-step explanation:
The powers are indicated by the value of the exponents, so move top down.
Answer: B
Step-by-step explanation: To solve you have to first multiply the number in front of the first pair of () by both numbers inside,then add that together. Then move on the the other pair of (). Multiply those together. Take the two numbers that you now have and add those to get the final answer.
With any equation you are allowed to take the logarithm of both sides so
5^c=125 now take the logarithm base 5 to both sides giving.
log5(5^c)=log5(125), using the rule log(a^b)=a*log(b) you get
c log5(5)=log5(125), since log5(5)=1
c=log5(125)
Answer:
D. 6x2 + 3x - 7
Step-by-step explanation:
50 km/h = 4 hours
60 km/h = x hours
50x = 60×4
50x = 240
x = 4.8 hours
